A review of Nix/NixOS after using it on all my machines for three years. I'll cover what works, what doesn't, and why it's the first OS that's stuck with me.
Is your hardware always the exact same? Because if it isn’t, then I’m sure you have to do modifications to your config file. And at that point you night as well just use a regular distro instead.
You can manage multiple machines with a single Nix configuration git repository and modularize the configuration as much as you want. You can have a config with a desktop environment that you skip on servers, override individual variables for a specific host or do whatever you want. You can even remote deploy it all with a simple nixos-rebuild build --target-host "user@host" and it works across different architectures too (e.g. build on your fast x86 machine and deploy to a slow RaspberryPi).
So what the main hassle of switching is that you have to run your hardware file to update for your new hardware, then inside your Nix config rarely will I ever have to edit things (maybe UUIDS if totally new machine fresh nix install/but I usually ssd swap for ease of transition and speed, or even clonezilla multiple drives and use as needed) even drivers for example. I’ve got auto scripts setup to run that will automatically pull any drivers or updates from the base system nix update to any drivers.
There’s really only two files you ever have to touch that I’ve used. Nix hardware, nix config. Once hardware is updated for which system you on you’ll never touch that until you boot a new machine with different hardware. If you setup nix how it’s supposed to be. Nix config is your master file. A single backup of that and when setup correctly. I can boot like I never left my machine. I’m talking librewolf still has my accounts open and logged in. VPN works. It’s all seamless damn near.
You have to learn to play within nixos sandbox meaning understand what your capable of doing and do it all inside config. With a few auto scripts, and 3 or 4 common commands on desktop page for whatever you wanna do and its terminal and memory hands off. I’ve what I call dumb Monkey commented my entire config and its in order if boot process from power on machine to boot, etc to shutdown.
A regular distro still poses many many more challenges when hardware swapping. You have different files to remember fstab, etc etc which can lead to mental memory load and system clutter if you didn’t build and maintain a perfect system from the beginning with stuff like files, sym links, all sorts if tweaks you’ve made over time.
So I switched to nix to mitigate those things. Now I’ve made a master config file copy, auto updates, backups, etc is all automated in the background now. All contained in my nix config. It’s supremely stable. Mental load is zero. Fills my use case. Immutable.
You have nothing to lose and only to gain. Pick any desktop environment and setup to your liking. I came from windows, to mint, to full custom nix all my apps, browsers, luks, apparmour, firejail, the whole stack.
I’ve tried live boots of many other distributions but this is the cleanest, leanest, most manageable of them all. My only true concern is project lasting long-term. For now. Aside from not having GUFW. I’m happy. I think there’s just a lot if misinfo and lack of hands on use from most people or incorrectly setup systems to utilize how nix should be ran. I think that should iron out over time.
